Abstract:
The Soil and Terrain database for Tunisia primary data (version 1.0), at scale 1:1 million (SOTER_Tunisia), was compiled of enhanced soil information within the framework of the FAO's program of Land Degradation Assessment in Drylands (LADA). A SOTER database was compiled based on the digital soil map of Tunisia. The primary soil and terrain data for Tunisia has been selected from available survey reports and publications. A SRTM-DEM was used to adjust some unit boundaries in the GIS file.

SOTER forms a part of the ongoing activities of ISRIC, FAO and UNEP to update the world's baseline information on natural resources.The project involved collaboration with national soil institutes from the countries in the region as well as individual experts.

Access Constraints
ISRIC - World Soil Information is pleased to make available a range of soil geographic and attribute data. Our databases were compiled using uniform methods (e.g., ISIS, SOTER, WISE). Strict quality-control measures were applied in developing the various databases but ISRIC does not warrant that the data are error free. Incomplete characterization data were available for many soil profiles because ... only selected measurements were undertaken during the original surveys. You are welcome to use the databases but you should be aware that the assessment of the accuracy and applicability of each dataset is strictly a USER RESPONSIBILITY; ISRIC takes no responsibility for problems that may arise from use of the databases. ISRIC requests you to acknowledge use of our data. This allows us to gauge the interest and usefulness of our services. Please refer to the data set documentation for suggested form of acknowledgement and citation. We kindly request that you send us two reprints of any publication that uses data received from ISRIC - World Soil Information. This will help us to determine the type and level of use of the data we distribute.
